APPARATUS FOR CARBURETING AIR.

SPECIFICATION forming part of Letters Patent No. 394,480, dated December 11, 1888.

Application filed October 5, 1887. Serial No. 251,531. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES M. FULKER- SON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Apparatus for Carbureting Air, of which the following is a specification.

My invention relates to that class of air-carbureting apparatus in which a pump is employed to force the air into the carburetor, said pump consisting, essentially, of a series of bellows arranged around a common center and adapted to be operated upon alternately by suitable mechanism, so that a constant supl ively, provided with perforated lugs d d', respectively, for the passage of the bolts or rivply of air to the carburetor is insured through suitable pipe-connections.

My invention consists in features of novelty to be hereinafter fully described, and then specifically pointed outin the claim.

In order that my invention may be fully understood, I will now proceed to describe the same -with reference to the accompanying drawings, in which- Figure I is a side elevation of a complete gas-making apparatus with my improved airpumping apparatus used in connection therewith, part of the operating mechanism being broken away. Fig. ILL is a plan of the pumpcasing with its top mechanism omitted. Fig. II is a vertical section on line .r Figs. Ia and IV. Fig. III is a detail sectional view on line III III, Fig. Ia. Fig. IV is a horizontal section on line Y Y, Figs. I and II. Fig. V is a vertical section on line Z Z, Fig. II. Fig. VI is a vertical section of one of the valves of the bellows. Fig. VII is a vert-ical section of one of the valves controlling the outlet of air.

Referring to the drawings, A represents my improved air-pump,B the carburetor, and C `the mixer, all of which have suitable pipe-connections, as shown, with each other.

D is a pipe leading from the pump to the carburetor, and provided with a valve.

E is a pipe for the vaporized air leading from the carburetor to the mixer C, which is also provided with a valve.

F is an auxiliary pipe leading from the main air-pipe D to the mixer, and also provided with a valve. This auxiliary pipe is for the purpose of supplying an additional quantity i l l of air to the vaporized air within the mixer, when desired.

G is the distriliuiing-pipe leading from the mixer.

A detailed description of the system just outlined is not necessary to enable those skilled in the art to use my invention, which lies principally in the air-puin ping apparatus. It should be understood that my pump can be used with any system wherein a pump is used for forcing air into the carburetor.

Referring now to said pump, a represents the cylindrical sheet-metal casing resting on legs b. The casing is strengthened by annular castings c c at the top and bottom, respectets e, wherewith the casing is secured to said castings. Between the ends of the casing at suitable intervals are arranged other castings, f, whereto the casing is bolted or riveted. Strengthening-ribs g, forming chords of a circle, are cast with said annular castings, and afford means for the attachment of bellows h, of which iive are shown, being' arranged around a common center. The movable leaves h of the bellows are hinged to the fixed leaves h2 thereof at h3, said leaves extending almost the entire height of the casing. The movable leaves of the bellows have secured thereon brackets i, provided with perforated ears i', for the passage of bolts Secured between Said ears by said bolts are armsj, which radiate from crank-arm k, secured removably on the vertical shaft 7c. Forming a part of the upper annular casting, c, is a diametrical crosspiece, c2, depending from which is a supporting-bracket, Z, perforated for the passage of shaft le. Said shaft is supported in said bracket by a removable collar, k2. For keeping the armsj on the crank-arm is a removable collar, k3, on the end of the latter. At the upper end of shaft k', above the crosspiece c2, is a gear-wheel, m, meshing with gearwheel `n on the horizontal shaft n, mounted in suitable bearing-blocks, o o', on the crosspiece c2. Loosely fitted on said shaft n, is a windlass, p, having a hollow trunnion, p', itting on the outer end of shaft n, and which also bears in block o. Said trunnion is squared at its end at p2 to fit in a square socket IOO of crank Q, for turning the Windlass to wind the rope thereon. A ratehet-wheel, R, having a collar, S, fitting on the shaft fn, is secured to said shaft by a pin, T, passing through the latter and said collar. Adapted to engage said ratchet-wheel is a pawl, U, pressed into engagement with the teeth thereof by a spring, V, so that when the rope is being wound on the windlass the shaft will not turn therewith, but when the rope s wound up and the apparatus started both will revolve. A rope, W, is adapted to be coiled around the windlass and to revolve the windlass through the medium of weight 7* and the usual pulley mechanism, s. On shaft n is keyed a handwheel, t, which is used when it is necessary to keep the pump going While the rope is being wound on the windlass. The fixed leaves of the bellows are provided with air-inlet valves u. Leading downward from the fixed leaves of the bellows are metallic exit-pipes fu, which converge into a common metallic trunk or chest, w, in the center of the bottom of the casing, to which is connected the pipe D, leading to the carburetor B. Check-valves .fr are located in the horizontal portions of pipes lv to prevent the air going from one bellows to the other. The bottom of the casing may be closed by means of semi-disks y y. The top of the casing may be closed by lianged semi-disks .z z.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

The combination, with the annular casing a, of the two'annular castings c c', arranged within said casing at its top and bottom, respectively, and having the lugs CZ and pinsV e for securing the casing to them7 the diametric cross-piece c2, having the perforation for the passage of a shaft, and the semi-disks y y and z z', detachably secured to the lower and upper castings, substantially as set forth.

CHARLES M. FULKERSON.
